Considering Winter Cereals? 2021 Variety Selection Data for Winter Cereals is Available

Yield results from the 2021 MCVET (Manitoba Crop Variety Evaluation Team) fall rye and winter wheat testing locations are available to help producers with variety selection decisions. Data from all locations was not available at the time of publication, more information will be included in Seed Manitoba 2022. Yield, agronomic, and disease resistance information for recently tested winter wheat and fall rye varieties are shown in the variety description tables (see tables below). Information on seed growers is found at the bottom of this article, or see the online Pedigree Seed Locator:

Things to keep in mind when looking through the data:

Comparing yields - Data provided in the yield comparison tables below helps to make comparisons between varieties at each site. Use the statistical information provided in the grey-shaded area located at the bottom of the table to see if differences between varieties are significant. To know if yield differences mean something, look at Significant Difference (Sig Diff) for each site, indicated as yes/no. If ‘yes’ then yield differences between varieties indicate real differences. When a site has shown significant difference, then the Least Significant Difference (LSD) value is also shown, indicating the number of bushels per acre (bu/acre) that varieties must differ by to be considered significantly different. For example, winter wheat varieties at the Arborg site must differ by more than 9 bu/acre to be considered significantly different.

Compare long-term yields – Yields at a single site, in a single year can be a poor indicator of how the variety may perform in your field in 2022. Look at long-term yield data or yields collected over many years and locations, to get a better indication of potential performance over a variety of environmental conditions. When choosing a new variety it is a good idea to look at past Seed Manitoba guides, available at, to see how consistently a variety performs across years and locations.

Agronomic and disease resistance - Yield is important, but other characteristics like maturity, height, standability, winter hardiness and disease resistance are critical to maximizing yield potential and quality.

Seed Manitoba 2022

Seed Manitoba 2022 will be available November 25, 2021. The guide will provide the 2021 small plot, replicated and unbiased information on post-registration variety performance of many crop types in Manitoba. Seed Manitoba is a collaborative effort between the Manitoba Seed Growers’ Association, Manitoba Agriculture and Resource Development, and the Manitoba Co-operator.

Anne Kirk is Manitoba Agriculture and Resource Development’s cereal crop specialist. Contributors to the early release of this data include MCVET co-ordinator Chami Amarasinghe, University of Manitoba wheat breeder Anita Brûlé-Babel, Agriculture and Agri-Food Canada barley breeder Ana Badea, as well as MCVET site contractors and funding agencies.
